Multimeter vs Voltmeter: Kodi pali kusiyana kotani?

Ngati mumakonda kugwira ntchito ndi zamagetsi, muyenera kudziwa kuti ma multimeter ndi ma voltmeters ndi zida zothandiza kwambiri komanso zofunika m'njira zambiri. Komabe, nthawi zambiri pamakhala chisokonezo kwa anthu ena kuti ndi iti yomwe ikugwirizana bwino ndi zosowa zawo. Ngakhale tili otsimikiza kuti mwina muli ndi lingaliro lachidziwitso chilichonse mwa zida izi, kuyang'anitsitsa kumatha kukhala kothandiza mukamagwira ntchito.

Kuti mumvetse bwino zida zonsezi komanso kusiyana kwake, werengani buku losavuta kumva. Tidzasanthula mawonekedwe a chipangizo chilichonse komanso momwe amasiyanirana wina ndi mnzake malinga ndi magwiridwe antchito.

Voltmeter ndi chida chosunthika chomwe chimangoyesa magetsi. Multimeter, kumbali ina, imapereka zosankha zambiri, koma imakhalanso yokwera mtengo pazifukwa zomwezo. Izi zimabweretsanso kusiyana kwakukulu pamitengo yawo popeza ma multimeter ndi okwera mtengo kwambiri.

Multimeter vs voltmeter: iti yomwe mungasankhe?

Ichi ndi chisankho chomwe muyenera kupanga kutengera momwe chipangizo chilichonse chimagwirira ntchito. Kwenikweni, zimatengera mtundu wa muyeso womwe mukufuna komanso kuchuluka kwa ndalama zomwe mungagwiritse ntchito. Pomvetsetsa zosowa zanu, muyenera kudziwa kuti ndi iti mwa awiriwa yomwe ingakuthandizireni bwino.

Werengani mosamala mfundo zotsatirazi za chipangizo chilichonse kuti mudziwe zomwe chilichonse chimachita komanso momwe chingakhudzire chisankho chanu.

Kumvetsetsa Ntchito ya Voltmeter

Ntchito yayikulu ya voltmeter ndikuyesa voteji yomwe idutsa pakati pa node ziwiri. Kuchokera pamalingaliro aukadaulo, volt ndi gawo lomwe lingathe kusiyana pakati pa mfundo ziwiri, ndipo kusiyana uku kumayesedwa mu volts. Mpweya wokhawokha umabwera m'mitundu iwiri popeza tilinso ndi mitundu iwiri ya mafunde monga Direct current (DC) ndi alternating current (AC). Ma voltmeters ena amangoyeza magetsi olunjika, pomwe ena amangoyesa kusinthasintha kwamagetsi. Ndiye mulinso ndi mwayi wosankha ma voltmeters omwe amayezera onse pa chipangizo chimodzi.

Kupanga kwamkati kwa choyesa magetsi ndikosavuta ndipo kumakhala ndi waya wocheperako wonyamula mawaya oyimitsidwa mozungulira mphamvu yakunja ya maginito. Chipangizocho chimabwera ndi zingwe ziwiri zomwe, zikalumikizidwa ndi mfundo ziwiri, zimayendetsa mawaya mkati. Izi zimapangitsa kuti waya achitepo kanthu ndi mphamvu ya maginito, ndipo koyilo yomwe imakhalapo imayamba kuzungulira. Izi zimasuntha cholozera choyezera pachiwonetsero, chomwe chikuwonetsa mtengo wamagetsi. Ma voltmeter a digito ndi otetezeka kwambiri kuposa mita ya singano ndipo akupezeka kwambiri masiku ano. (1)

Eversame Flat US Plug AC 80-300V LCD Digital Voltmeter

Ngakhale choyezera voteji chomwe chafotokozedwa pamwambapa chimayeza mfundo zosiyanasiyana, mutha kupezanso zida zochotseka monga Eversame Flat US Plug AC 80-300V LCD Digital Voltmeter, yomwe imawonetsa voteji ikuyenda kudzera pakhoma linalake. Amagwiritsidwa ntchito poyang'anira zida zomwe zalumikizidwa m'malo ogulitsira ndipo zimathandizira kupewa kuwonongeka kwamagetsi komwe kungachitike ngati mphamvu yaphulika.

Kodi multimeter imachita chiyani?

Chinthu chimodzi chomwe multimeter ingachite ndikuchita ngati voltmeter. Chifukwa chake, ngati mutagula ngakhale multimeter ya analogi, mutha kukwaniritsa zosowa zanu za voltmeter. Multimeter imatha kuyeza ma voltage ndi mayunitsi amagetsi monga apano ndi kukana. Ma multimeter apamwamba kwambiri amayezeranso magawo monga capacitance, kutentha, ma frequency, inductance, acidity, ndi chinyezi.

Zomwe zili mkati mwa multimeter zimakhala zovuta kwambiri ndipo zimaphatikizapo zinthu zina monga resistors, capacitors, sensors kutentha, ndi zina. Kuchokera pamalingaliro aukadaulo, ndizosavuta kuwona kuti multimeter ndi chida chogwira ntchito kwambiri kuposa voltmeter yosavuta.

UYIGAO TRMS 6000 digito multimeter

Chitsanzo cha voltmeter yogwira ntchito kwambiri ndi UYIGAO TRMS 6000 digito multimeter, chipangizo chomwe chimapereka njira zingapo zoyezera zomwe mungasankhe. Ndi chipangizochi, mutha kuyeza mayunitsi ambiri oyezera, kuphatikiza kutentha, capacitance, AC voltage, AC current, DC voltage, DC current, frequency, and resistance.

Chipangizochi chimaperekanso zinthu zina zapadera monga beep, auto ndi manual range, NCV kuzindikira, ndi kuzimitsa galimoto kuti musunge mphamvu ya batri. Chipangizochi chimakhalanso ndi chiwonetsero chachikulu cha 3-inch chomwe ndi chosavuta kuwerenga ndikuwunikiranso. Ndizoyenera kugwiritsidwa ntchito mwaukadaulo ndipo zimakhala ndi nyumba yolimba kuti zisawonongeke zikagwa. Mukhozanso kuziyika pamalo athyathyathya pogwiritsa ntchito choyimira chophatikizidwa.

Kufotokozera mwachidule

Pakalipano, mwinamwake mukumvetsa kale kuti zipangizo ziwirizi ndizosiyana kwambiri ndi momwe zimagwirira ntchito. Voltmeter ndiyosavuta koma imatha kubwera mumitundu yosiyanasiyana ndi makulidwe kuti igwiritsidwe ntchito mokhazikika komanso yosavuta. Ndi njira yotsika mtengo ya ziwirizi, koma izi ndi chifukwa cha ntchito zake zochepa. Ma Multimeters, kumbali ina, ndi zida zosunthika kwambiri zomwe zimatha kukugwiritsani ntchito zosiyanasiyana, koma muyenera kutulutsa ndalama zambiri ngati mukufuna. Ganizirani za zosowa zanu ndipo mutha kusankha mosavuta zomwe zingakusangalatseni.

Onani zina mwazolemba zathu pansipa.

• Momwe mungayesere magetsi a DC ndi multimeter
• Momwe mungawerenge multimeter ya analogi
• Chizindikiro chamagetsi a Multimeter
